Title: Stretch film and method for manufacturing the same
Inventor: KATANO ICHIRO
IPC: B29C48/305
Filed: 2001-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a stretch film being a non-polyvinyl chloride single-layered stretch film, not torn when stretched by overlap packaging in both of automatic packaging and hand lap packaging and good in other packaging properties.
